Small outdated 26 inch wheels, ugly, looks very heavy.

Promo pictures look cringe with metrosexuals riding them on a gravel road.

Cool.

Typical 2020s design trying to appeal to the smartphone/sedentary crowd who know nothing about bikes.

For this kind of money you can get a really nice eMTB like the Mith from UNNO which has 29 inch wheels, weighs 47 lbs (21.3kg) and is a much more capable bike with a 800Wh battery.

If you don't want classic transmission there are other eMTBs with a Pinion gearbox:

I tend to agree with comments that point out that 'modern' e-bikes are really electric motor cycles or the original "MoPed" from the 60's. And they have the same appeal, relatively cheap to operate, fit in between regulatory categories, don't require a garage to store, Etc. E-scooters aren't much better (just worse kinematics). That said, I never thought the Segway was ever going to be more than a 'niche' product whereas I had already lived in a city[1] with thousands of mopeds. To the extent they are embraced by urban planners with reduced parking mandates and their own roadways I think they are a net win for cities, when they terrorize pedestrians on sidewalks, not so much.

Adjusted for inflation the Segway would be close to $10,000 today after taxes.

That price tag and the way overhyped lead up to it's unveiling combined to kill any chance the Segway had. Dean's (RIP, I think) vision might have had a chance if it wasn't the same price as a lightly used new-to-me Kia Sephia.

At even half the $5000+ price it would have found a lot more adoption. Tourism companies still use the shit out of them and once they start dumping them, I bet they'll be the cool thing to have.

I think that the Class 1 and Class 2 and Class 3 regulations when properly followed tell you what you are getting. Since this is Class 3, it really is close to a Moped and has a lot more restrictions depending on your area similar to a motorcycle but still allowed on city streets without insurance in most places in the USA, but often has restrictions in parks etc.

The problem is that many other manufacturers have “selectable” class which really is meaningless and doesn’t really tell you what you are buying and often times is really close to a motorcycle.

If I were buying a bike for my young child I would stick to class 1 or 2.

There are plenty of modern ebikes that are just bikes with a motor. I have one of these for instance (well, the previous generation): https://ride1up.com/product/roadster-v3/

The best description I've seen of using it is "cycling without hills".

The fact that we use the same name for these and "low speed electric motorcycles" is... unfortunate.

It depends on what you mean with an e-bike, most e-bikes are pedelecs.

That means they don't have a throttle which is what a motorcycle or moped has.

You have to pedal to get an assist, this can either be a hub drive or a mid drive motor which have different characteristics (that's another story).

Mopeds but with crappier seats. Mopeds at least had decently comfortable seats and could seat a passenger —if we’re considering normal BMI folks.

Moped seats are for sitting, bike seats are for pedaling.

They're not worse, they're different because they need to be.

So the interesting thing about this is the ... peddle-by-wire drivetrain? So unlike a normal e-bike, when its battery dies it turns into a stationary bike.

I love ebikes and generally like what Rivian does, but in a very competitive market it's hard to see the appeal of this.

adrianmonk

I would hope they designed it where you can keep riding. It seems possible. Pick some charge level (say 20%) and provide less and less power assist as you approach that. Once you hit 20%, a control system tries to keep it about 20% charged. Basically you enter a mode where the battery becomes a buffer (between the pedal and wheels) rather than a power source. The bike would feel sluggish, but it wouldn't stop working.

Maybe you pedal the generator on the kickstand for a minute to give it enough charge to operate the electronics, and then away you go working hard like on any other e-bike that's out of charge? I don't see why it couldn't move.

Just don't think of it as an e-bike.. Think of it as an electric scooter with a built-in, manual charging solution. The question then seems to be how well it compares against other electric scooters?

In the next sentence:

"It features a new pedal-by-wire drivetrain called “DreamRide” developed in-house. The rider pedals a generator, which replenishes the battery,"

Yes, the motion->electric->motion circuit is not as efficient as direct pedal but you are explicitly not stranded.

blacksmith_tb

If that worked well though, why pack a large battery in the first place? My suspicion is that pedaling provides a small percentage of the energy needed to move you and the bike and your cargo.

tree_enjoyer

an hour ago

A traditional bicycle chain drive is something around 98% efficient - particularly if you're using internally geared hubs or a single speed with the chain line perfectly straight. What's a typical consumer alternator efficiency? Maybe 85%? And then a few steps for losses in the charging circuit and then again at the motor.

Not even napkin math, but ballpark I would think you're looking at having to pedal about 20-25% harder to accelerate the same rate compared to a chain, with no supplemental energy directed towards charging the battery (though I would assume al the energy goes through the power management system anyways).

However you get some gain in that you don't have to select a gear ratio, and that the electric motor provides torque efficiently at any rpm you can realistically expect on a bicycle. If it has an adaptive resistance level it will probably be more work (energy) but for many non-cyclists feel much more intuitive and simple

pm90

I think the idea is to disconnect pedaling from road conditions.

When you’re biking, it’s preferable to pedal in “safe” zones (protected bike lanes, trails etc.) while relying on the battery for eg intersections and when sharing the road with vehicles. With a regular bike you have to pedal harder precisely at these zones which makes it a little scary. You can also pedal on fairly flat ground/use all that energy to climb up a steep hill quickly without pedaling etc.

andyferris

an hour ago

Exactly.

My government says the trigger (accelerator) is bad and made it illegal.

In usage, however, I feel WAY safer being able to accelerate (from standstill) through intersections. I once had a chain break at an inopportune moment while doing that - scary! Now my rear hub motor means there's no danger anymore.

charging by pedaling is just for range extension. obviously you aren’t breaking the laws of thermodynamics on an e-bike.

Lance Armstrong can sustain about 450 watts. Rec cyclists maybe 1/4 that. E-bike motors are 250-500w. So not a small percentage but also not enough to be sustainable unless you are a world class athlete.

Are you doing a bit? I’m worried I’m about to be the joke ruiner :) The battery is included so you don’t have to pedal. When the battery is out, you can pedal. The only thing I can come up with is you think it is literally impossible or extremely difficult to pedal an e-bike when it is out of battery. it’s not fun but the incremental battery weight is as if you gained 20 lbs, not impossible.

Edit: oh I see above there’s subtle confusion building over the thread that this is a new feature of e-bikes, as of this Rivian marketing. it is not.

If I may also peddle my opinion, this e-bike is a fresh innovation and it's easy to see how revolutionary it is. What very competitive market has regen, 180 newton-meter of torque, programmable power curve, shape-shifting? This e-bike is incredible. These days, who lets their iphone battery die?

A phone can get charged with random 5V outlets and you can walk around with a 200g battery to make it last two days.

The bike won't fit any of that until there's hot swappable batteries sold everywhere, and when it's dead you'll be pushing it back home.

I don't think the pedals are attached to the drivetrain. They look like they are literally just to charge the battery. So this bike is just dead when it's out of batteries? Unless I'm missing something.

Horses were not cheap nor universally available. And cars had the obvious benefit that they did not leave literal horse shit around the city.

This "revolutionary design" does not offer any significant advantage over the existing systems for e-bikes. A regular e-bike without power is a just a regular bike. You can adapt a regular bike into an e-bike for < $600. Any run-of-the-mill mechanic can figure out how to work on a basic bike. This one will probably require some "certified Rivian expert" to work on it.

Only irrational neomania can justify being interested in this "revolution".

I ride a motorbike. I'd argue speed is the limiter.

Some of these electric bikes are quite speedy - capable of mixing it up with flowing traffic. So classify them as being motorbikes.

If they can't go that fast, or are "assistive only" (require large fraction of rider pedal input up to a set speed) then legislatively they are a "normal bike".

The thing is, we already have the rules around what each style of bike. It's just a classification thing.

808Wh battery and 100 miles of range. These two numbers track with each other and are roughly believable.

OTOH, with a battery this big, a generator powered by the pedals, and regen braking this thing has to be heavy. I'd expect it to weigh at least 80 lbs. More likely 100. The fact that their "specs" say nothing about weight suggests they're embarrassed about the weight.

dylan604

My eBike is close to 90lbs, but it is a large cargo bike touted as a "small car replacement". It is close to a tandem bike in size with a steel frame. I'm so used to it now, but I live in a house and never need to carry it up stairs. It does mean that I need an expensive bike rack to support that weight.

newsclues

I lived in an apartment with only stairs where I owned a light gravel bike roughly 20 lbs and an old mtb that was about 35, and my back really felt the difference between the two.

100 lbs would be unmanageable.

dylan604

36 minutes ago

With a bike the size of mine, I don't think I would own it if I was living in an apartment. It's just too big even without considering stairs. It's long. It's wide. It's perfect for how I'm using it not in an apartment. Not every bike is a fit for every rider.

The point I really fell like I left out is that with that size and weight of the bike plus being able to haul 300lbs, the motor and battery combo is rated for 45 miles. Not once have I felt like I needed longer range. It's not that kind of bike. I use it for tooling around while shopping or leisure rides topping out at 35 miles. Even at 35 mile rides, by battery still has plenty remaining as I still heavily rely on my meat motor.

My Stromer ST3 weights about 30kg, has an 1kWh battery but doesn't come anywhere close to even 100km range at full speed.

I suspect pedal-by-wire will only be slightly heavier since it doesn't need gears, but the range will probably be even worse.

Regen braking is how you can tell this was designed by a moron. The energy balance simply does not favor regenerative braking on a bicycle, especially a bicycle that flippantly ignores aerodynamics like this one does. A bicyclist loses roughly all of their energy to air resistance. It's not a truck. There is not substantial potential energy to be recaptured going down hills.

edaemon

3 hours ago

What do you mean? The regenerative braking only kicks in when you engage the brake lever. It's not going to add much range but it's free, I don't see any downside to including regenerative braking.

linkjuice4all

2 hours ago

You're going to have a difficult time pulling a lot of energy out of the back wheel as you're slowing down. The more you decelerate the less weight you've got on your back wheel. Eventually you reach the maximum energy transfer from back wheel contact patch into the motor and lock up the back wheel, and even then you may not have considerably slowed the bike.

Regen on the front wheel would be most effective - but then you've got two motors or a less-than-ideal front motor that adds unsprung weight and has similar traction issues during acceleration as the front unloads.

It's a shame - I think a lot of people want ebikes to work, but they're not as convenient as a pedal bike (especially not in small apartments) and usually they're too heavy to really use in blended pedaling/e-assist mode.

jeffbee

3 hours ago

It isn't free. How could it be free? It requires at least an electronic control system and a pressure sensor.

numpad0

2 hours ago

3-phase motors are controlled by torque commands into the driver. Give it a value and it generates requisite voltages to fill the gap between current state and desired state. Give it a positive value and the driver spins up the motor, give it a negative and it artificially spins down the motor progressively by commanded amounts. So especially off-throttle regen is completely free. IIUC.

edaemon

3 hours ago

It's the same control system that operates the motor. The motor is just being used as a generator.

I'm not sure which pressure sensor you mean, like in the brake lever? E-bikes with hydraulic brakes already have sensors for power cutoff (and in this case for brake lights).

cyberax

2 hours ago

If you engineer it properly, it doesn't add _any_ weight or complexity. All you need is a bit different arrangement of power transistors and some software.

Why existing bikes don't use it? Because you need software or a more complicated controller, and the amount of regenerated energy is indeed not that large.

Not a big cyclist but is that still true for lower speed city riding (typical to flat european cycling prone countries), hillier SF, or mountain biking?

It seems obviously true to typical racing or distance scenarios. And i notice the wind even at lower speeds on e-bikes in SF.

But between their quad scenario and what I imagine as the urban car replacement scenario it doesn't seem as obvious.

jeffbee

3 hours ago

Yes, it is true at all speed and under all conditions. The system simply does not have the mass that would give it a great deal of gravitational potential energy, and it reaches a power equilibrium with the air at low speeds. Example:

100kg rider at 15 kph = .24W-h kinetic energy. At this speed there is probably roughly 11N of air and rolling resistance, so the steady state power is about 3W-h per km. If you go 1km between stops, or more, the amount you can expect to gain by regeneration is extremely small. It could perhaps extend your range by 5%, generously.

big_toast

3 hours ago

Does that assume no pedaling though? In my experience the pain of starts and stops dominates the joy of steady state pedaling. Presumably the 3Wh/km is free/"exercise" or some portion. Whereas the .24Wh (re-gainable w/ some loss) is all sweat and pain imo.

If I'm understanding the math, maybe that scales the regenerative range extension % by your tolerance for pedaling?

adgjlsfhk1

The difference is that humans (unlike motors) have pretty low max power limits.

big_toast

I assume this comment in relation to the starting from a stop being unpleasant?

If it's w.r.t. effect of low max power on low cumulative generation, I agree it does seem like a little silly to arbitrage your power generation this way. But maybe the tradeoff is worth it in some circumstances in their view?

Or maybe it's just a low cost addition as other commenters say.

As someone who enjoys bicycling every now and then, I suspect a 40 kg Also TM-B hurling up a tight bicycle lane at 50 km/h can be somewhat hazardous to people on regular (unpowered and light) bicycles—not unlike a motorcycle, but obviously to a lesser degree.

For comparison, Seoul bike lanes allow pedal-assist bikes that are limited to 25 km/h and weigh no more than 30 kg (battery included), which seems pretty generous.

a full suspension e-bike, 500+Wh battery, with a belt drive for $4,500 is honestly a really good deal. There is a shortage of options when it comes to full-suspension bikes that are good for commutes. Compare this to any e-bike with the Bosch e-bike system. The big risk here for consumers if whether they can match the service, support, and reliability that Bosch has. There appears to be a class-2 e-bike option which is something that significantly differentiates it from bikes with the Bosch system.

In the U.S., there are 3 classes of e-bike: Class 1: pedal-assist only up to 20mph (helmets optional for adults) Class 2: same as Class 1 but with optional throttle to 20mph Class 3: pedal-assist only up to 28mph (helmets required, adults only)

There's also a maximum power rating of 750 watts for all of these. I'm not sure where the "pedal by wire" feature is from a regulatory perspective, but to me this fits into either class 2 or 3 depending on what option you get.

Based on the video and rivian history I think they wanted to redesign from the ground up a bike to match the packaging success they had at rivian and companies like lucid vs how legacy automakers approached it. The problem is the current laws about bikes and ebikes limited them and they had to make many tradeoffs which is what we are looking at. I guess we will find it if it was worth it to go ground up vs more off the shelf. As a rivian owner I'm concerned about repair-ability and maintenance.

The way I read it is if you use throttle-only you can reach 20 mph, but then if adding pedal-power you reach 28 mph. The pedal is probably not generating sufficient force to add 8 mph, but it’s telling the control system to do that.

jlhawn

class 2 and class 3 are mutually exclusive. You cannot legally have an e-bike that supports throttle up to 20mph that can also continue to e-assist if you pedal up to 28mph. While it's technically possible in software to switch between these modes, consumers aren't supposed to be able to do this on their own.

You can usually limit the bike to go less than 20mph in those cases.

It would be nice to have the GPS automatically set the pedal assist max speed when riding on shared paths with pedestrians and people.

I have also seen road bikers on those same shared paths pedal faster than 20mph.

No consumer GPS is precise enough to reliably distinguish between a bike path and an adjacent regular road, especially if there are any overhead obstructions nearby. Many bike paths don't have a 20mph speed limit anyway.

I acknowledge the utility of e-bikes for many; for me, I prefer my non-e bike when I want to ride my bike, but would love an e-motorycle as an alternative to 80% of my car trips.

> Also also unveiled its Alpha Wave helmet.... It also features integrated lights and a four-speaker, wind-shielded internal audio system with two noise-canceling mics. The helmet integrates with the TM-B’s console, where music, calls, and podcasts can be controlled on the bike.

In an ideal world these would be great features to have, but in the real world, where so many places have a near complete absence of safe cycling infrastructure and bicycles are casually mixed in with giant trucks it's a bit of a scary notion to reduce your situational awareness with a great sound system and the distraction of doing your morning zoom standup while cycling to work (I've done this before lol, tho most of my commute is in separated bike lanes...).

This points to the headwinds to adoption and success of the Also, which is that so many cities are ambivalent and uninterested if not outright ideologically opposed to building safe all ages and abilities bike lanes. That sort of safe infrastructure is critical to the success of a product like this. It's really unfortunate.

I have a 750W e-bike (which actually means 750W peak, 500W sustained).

There are hills near my house that my bike can not make it up without significant pedal assist.

If the motor and power electronics on this e-bike can only handle 750W peak, 500W sustained, as is common and I think is possibly even legislated in parts of the U.S., this bike will not be able to make it up serious hills.

With a normal e-bike, your pedaling is additive to the motor. That is not the case with this design.

If the motor is geared it could make a difference. For comparison, most people put out about 100 watts with their legs, but need to downshift to go up hills. This looks like a mid drive unit, which should be capable of varied gearing.

While this looks pretty slick, i definitely agree with commenters this falls on the moped end of things. I will assume from the features listed that it's loaded with proprietary parts.

I'm an everyday cyclist and when people ask me for recommendations on bike, I almost always recommend they look at traditional bike brands with e-bikes, rather than pure e-bike brands.

Traditional bike shop level bike brands typically have reputable Bosch or Bafang motors (preferably mid drive, not in the wheels hub)and computers, but the rest of the bike will be mostly standard bike brakes, wheel sizes, derailleurs, chains, hubs etc.

Bring one of those DTC e-bike brands into your local shop and there's probably a 50% chance they'll work on it. Good luck finding replacement parts or getting support from the company with no local prescence.

Look on /r/bikemechanics to see the horror show working on some of these bikes has become.

One of the great things about cycling is that almost anyone can learn to fix and maintain their bike. It's affordable and mostly standardized at this point

It's extremely accessible with YouTube Videos, the Park Tool Blue Book, and bike coops or workshops in most cities. Many local shops are happy to share knowledge with their customers.

The closer your e-bike is to a traditional bike, the better time you'll have in the long run.

Not affiliated but I'm looking into converting my commuter bike with a kit from https://ebikes.ca.

I disagree, I went that route and ended up regretting it. While converting a regular bike to an e-bike does work, a standard commuter bike is designed to carry a person’s weight with the center of gravity in mind. Adding an electric hub motor and a 20 lb lithium battery to a frame with cantilever brakes just feels sketchy. A properly designed e-bike typically comes with four-piston hydraulic brakes, and the placement of the motor and battery is engineered to maintain balance and handling.

Bear with me I don't know much about bikes but I have this honest question: why does it need a chain, and won't place the engine (or whatever gear box it has) directly on the wheel?

roadside_picnic

6 hours ago

Dirt bikes and many motorcycles also have chains, this allows you to change gears to adjust torque (alternatives include shaft and belt drives).

E-bikes can have the motors on the wheel (hub-drive) or on the pedal (mid-drive). This choice is largely related to how much you want your e-bike to really be a scooter or really be providing pedal assist. As a consequence hub-drive e-bikes typically have a throttle while mid-drive do not.

A good mid-drive e-bike really makes it feel like you are a super human cyclist rather than riding a scooter. It leads to a much smoother riding experience if your aim is to still be essentially bicycling but you'd like to get moving faster and not break a sweet even on the most extreme hills.

dreamcompiler

I have a couple of mid-drive e-bikes (Bafang motors) with throttles. Throttled mid-drives let you get the best of both worlds: Great pedal assist combined with the ability to just be a scooter when you get tired. And I agree that mid-drive is the way to go if you want to ride on hills. If you commute in San Francisco for example, a hub drive e-bike will not help you much but a mid-drive will change your life.

Of course. But the pedals on this thing aren't even connected to the drivetrain. So what is the benefit in this specific case?

Completely agree. They should probably just remove the pedals and generator entirely and save that weight. But then legally it becomes a scooter and probably would require a license and be more limited as to where it could go.

But what if the pedals are connected to the wheel only in a "symbolic" way, say, some electrical contact or something? So technically you still have to pedal to qualify as e-bike, just without real mechanical transmission? And if you lose power bad luck, don't commute with an empty battery...

soco

I could imagine (not necessarily feasible!) the pedals only moving a dynamo with variable resistance to mimic real world pedaling, and the hub drive doing the drive according to the pedaling speed? Would that be a scooter or a e-bike, according to norms?

bullfightonmars

6 hours ago

Putting the motor into the wheel makes for an excellent riding experience, I have a Bionx rear wheel (out of business) that is connected to the chain ring and pedals in the traditional way. The wheel detects torque from pedaling and applies it's own torque to drive the wheel. It can be used with and without power and feels almost seamless and is silent.

Unfortunately it seems to be difficult to engineer and build these wheel motors for reliability and longevity. They significanly increase the unsprung mass of the wheel which leads to increased wear on the hub components.

STKFLT

6 hours ago

The biggest reason is minimizing unsprung mass, the performance of the rear suspension would be much worse with a hub motor.

Groxx

6 hours ago

does that actually matter much on anything except dirt-bike tracks, or trying to go 40mph on a horrifically bumpy track? minus some comfort advantage, of course.

like technically, sure, it's obviously true. but for performance it only really matters when you would get air time with higher mass, and the lower mass stays in contact more. commuter e-biking generally doesn't get anywhere near those speeds or bump-sizes. (trail biking: sure! I 100% believe it's a sizable consideration there)

STKFLT

5 hours ago

I've never ridden a full suspension with a hub motor so I can't say, but my guess is that yes, it would make a pretty big difference with an aggressive rider or poor quality streets. It's not just keeping contact that matters, its the consistency and quality of contact, especially with a super torquey motor ready to jump at a twitch of your thumb. Its of course not necessary for commuter biking, but neither is basically anything on this premium product aside from the wheels and pedals.

Also to note, they are very much marketing it as a trail bike in addition to a commuter so it's not surprising they would spend a bit to optimize for ride quality and traction.

Not all e-bikes have a rear suspension, so the motor will feel the bumps either way pretty much the same, I would guess. Or being placed in the middle halves somewhat the shocks?

A touchscreen on a primarily-outdoor device makes no sense to me. It's just a single point of failure for fanciness. Transit safety should be taken more seriously, with controls you can operate by feel, rather than vision. It's not important if lots and lots of companies include this single point of failure.

Edit: also, don't capacitive screens kinda suck if they get a little wet? like what, you just can't use the screen controls while it's raining without risking unlocking your seat 40,000 times in a half second due to a stray raindrop sitting on the screen? Feels like resistive would explicitly be superior here. You probably don't need huge accuracy for what should ideally be a spacious display anyways.

Hydraulic disc brakes are not overkill with a bike of that mass [0] and power. Disc brakes are very common mountain bikes or any type where there is a lot of braking as caliper/rim brakes can overheat and pop the tires, so this unit should definitely have disc brakes. Hydraulic is better than cable/mechanical as hydraulic can generate more braking power, have better feel, and stay in better adjustment. The only downside vs cable+disc is cable is more repairable in the field.

[0] (overall specs indicate a lot of weight, Rivian are not proud enough of any lightweighting to even print the weight, and their autos are also very heavy, indicating a lack of lightweight engineering discipline in that shop which may carry over to their other mobility solutions)

The battery system here sounds so sweet. Swappable, with a respectable 0.5kWh and then an Extended Range 0.8kWh is excellent.

Usb-c chargeable at 240W is divinely sweet. Maybe maybe some day dual USB would be nice (for the ER especially) but this is quite respectable. And by not trying to super fast charge the battery will live longer anyhow.

Being removable is another nice win, if not uncommon. I don't know which other batteries provide USB power even without the bike, which again is such a great nice to have: take the bike to a park then bring with an charge some phones or what-not.

In the future I really hope we see some battery alliances, making some form factors, and centralizing on usb-c. As would be good common sense. The overlap between a bike battery and standalone Delta or Ecoflow battery power station is huge, and Rivian here seems a little further along than most at hybridizing & generalizing a battery system: obvious win to anyone paying attention!

The modularity could be a major win too. I'd love to see a an e-bike maker go down the Ford Bronco path & add a bunch of attachments points and replaceable/modular pieces to the design, and release all the specs for free use! Even if it only is Rivian and some partners doing this here, this is the way, it feels like:

> The top frame of the TM-B is modular by design, so the bike can be transformed without tools into a cargo hauler, kid carrier, or cruiser with a bench seat.

Cargo haulers easily climb to the 6000$ ranges. And the massive 180NM motor here will not bat an eye!

One thing I'd love to see: a stationary bike mode. Bring it inside for the winter & do spin class, charging up the battery. The full series hybrid, no mechanical linkage, doesnt deel super super practical to be honest but it's interesting!

A lot of nice basic things that make sense. Like no longer needing special cherging equipment for reasonably good capacity chwrging (albeit most usb-c chargers will only be doing 100w for a while now, but that seems fine).

bikes are already highly "modular" in that outside of ebike motor systems you can swap most parts. Bikes like the Rivian in the article would only work if ruggedized and sold to fleets.

Agreed that bikes do often exhibit some level of modularity. But attaching a front or back cargo rack or kid carrier gets pretty finicky pretty quick: most e-bikers tend to just buy the (often quite expensive) 1st party gear, because it'll actually fit right.

This bike seems to have only a single major modular system, but it comprises such a massive part of the bike: there's a big stem-post that attaches to the drive unit. Being able to swap that stem-post out for other things allows for really big changes, imo. You could build some really cool really neat different top-sides atop this bike, with really weird cargo or kid shapes.

I would love to see smaller level modularity too. I'm really impressed by the Bronco, and how they've clearly worked very hard to make it a "car as a platform", opening up as much space as they can for aftermarket parts & 3d printing people to build everything from cup-holders/interior fixing to body-panels (dunno the best link for this, but for ex: https://thebronconation.com/more-bronco-modularity-fender-fl...). I see Rivian / Also tapping that energy here in a way that moves far beyond what bikes today offer.

That said, when I was living in NYC, I was always afraid that someone on an e-bike would hit me when I'm trying to cross the road (esp. in the evenings or when the weather doesn't permit a lot of visibility). Some of these e-bikers also ride on the pedestrian platforms and it's dangerous (as of 2022, I don't think there was any enforcement to keep them out of the platforms).

It'd be interesting to see if/how e-bike laws would evolve if this trend gets bigger (ebikes are already big in big cities like NYC)
